B-LINE P3BEHD3070G – Frequently Asked Questions
1) What amperage and interrupting rating does the B-Line P3BEHD3070G plug-in unit carry?
The P3BEHD3070G Pow-R-Way III plug-in unit is a 70 amp device built on Eaton's E frame, which spans 15 to 225 amps. Interrupting capacity is 18 kAIC at 240 Vac and 14 kAIC at 480 Vac, so the available fault current at the busway tap point has to sit at or below those numbers for the application to be legitimate. On a 480 volt system with higher available fault current you need a higher interrupting device, not this one.
2) Will this Eaton Pow-R-Way III plug-in unit fit any manufacturer's busway?
No. The P3BEHD3070G is a plug-in unit made for Eaton Pow-R-Way III busway. Busway plug-in openings and stab arrangements are proprietary to the run they were built for, so it will not land on another manufacturer's busway or on an older Eaton busway family. Confirm the run on the job is Pow-R-Way III before ordering.
3) Does this plug-in unit include a ground path, or do I have to pull a separate equipment ground?
The P3BEHD3070G is built for 50 percent internal ground, meaning the busway housing carries the equipment ground at 50 percent capacity and the unit is configured to pick it up. Match that to the ground configuration of the busway run itself; a unit ordered for internal ground on a run that uses a separate ground bus is the wrong unit.
4) How big and heavy is the P3BEHD3070G, and can one person hang it?
It measures 21.2 by 12.36 by 5.43 inches and weighs 25 pounds. That is a two-hand lift overhead at busway height, and most crews hang a unit this size with a second person or a lift, especially when the run is at ceiling level. Check clear working space below the plug-in opening before you schedule the hang.
5) Is the P3BEHD3070G a breaker unit or a fusible switch unit?
It is a circuit breaker plug-in unit, not a fusible disconnect. The protection is a molded case breaker in the E frame range, so there are no fuses to stock or replace after a fault, and reset is a handle operation. If the facility standard calls for fused protection at the tap, this is not the unit to order.
6) What is the exact part number to order for a 70 amp Pow-R-Way III breaker plug-in with internal ground?
Order B-Line P3BEHD3070G. That single catalog number covers the 70 amp E frame breaker plug-in with 50 percent internal ground, rated 18 kAIC at 240 Vac and 14 kAIC at 480 Vac. Amperage, frame, and ground configuration are all baked into the number, so there are no suffixes to add.
7) Can I use this 70 amp plug-in unit for a larger load later, or do I need a different unit?
The breaker in this unit is fixed at 70 amps. Because it sits on the E frame, which covers 15 to 225 amps, Eaton offers sibling Pow-R-Way III plug-ins across that range, so upsizing means a different catalog number rather than a change inside this housing. If the load is growing, size the unit for the future load now and keep the busway tap opening the same.
